Happy new year! (v1.x)

Fixes #94

This backports a fix from v2.x which adds the builtin version of pcre as
a static dependency, rather than relying on the OS to provide pcre

 Git implementation of the Godot Engine VCS interface in Godot. We use [libgit2](https://libgit2.org) as our backend to simulate Git in code.
 
-> Planned for the upcoming version of Godot. Look for other branches for support in other Godot releases.
+> **Works only for the Godot 3.2.x-3.4.x releases. Look in other branches for support in other Godot versions.**
 
 ## Installation Instructions
 
-1.  Grab the platform binaries here: <https://github.com/godotengine/godot-git-plugin/releases>
-2.  Then read the installation instructions: https://github.com/godotengine/godot-git-plugin/wiki
+ 1. Grab the platform binaries here: <https://github.com/godotengine/godot-git-plugin/releases>
+ 2. Then read the installation instructions: https://github.com/godotengine/godot-git-plugin/wiki
 
 ## Build Instructions
 
-This section onwards is only meant to be used if you intend to compile the plugin from source.
+### Pre-requisites
 
-### Required Tools
+Required build tools:
 
-- Full copy of the source code. Remember to use `git clone --recursive`.
-- [SCons](https://scons.org/pages/download.html) (v3.0.1+)
-- C++17 and C90 compilers detectable by SCons and present in `PATH`.
-- Platforms Specific Setup
-  - Windows
-    - No extra steps required other than setting up the compilers.
-  - MacOS
-    - For making universal builds targeting both Apple Silicon and x86_64, you can optionally run `build_openssl_universal_macos.sh` to build OpenSSL yourself and replace the already prebuilt libraries provided inside `thirdparty/openssl/`, otherwise, just run `brew install openssl@1.1` to use the prebuilt libraries provided in this repository.
-  - Linux
-    - Run `sudo apt-get install libssl-dev`, or your local package manager's equivalent.
+* [CMake](https://cmake.org/download/) (v3.5.1+)
+* [SCons](https://scons.org/pages/download.html) (v3.0.1+)
 
-### Release Build
+### Windows
 
-```
-scons platform=<platform> target=editor -j 6
-```
+> MSVC is our recommended compiler for Windows
 
-> You may get the gdextension dump yourself from Godot using the instructions in the next section, or use the ones provided in `godot-cpp/gdextension` or `ci/`.
+1. Load the x64 command prompt: `x64 Native Tools Command Prompt for VS 20XX`.
+2. Run ```build_libs.bat Release```.
+3. Run ```scons platform=windows target=release```
 
-For more build options, run `scons platform=<platform> -h`
+### Linux
 
-## Dev builds
+> G++ is our recommended compiler for Linux
 
-When new features are being worked on for the Godot VCS Integration, the build process sometimes requires developers to make changes in the GDExtension API along with this plugin. This means we need to manually generate the GDExtension API from the custom Godot builds and use it to compile godot-cpp, and then finally link the resulting godot-cpp binary into this plugin.
+1. Prepare script for execution: ```chmod 755 build_libs.sh```
+2. Run ```. ./build_libs.sh Release```.
+3. Run ```scons platform=x11 target=release```.
 
-If you need to use a custom GDExtension API:
+### MacOS
 
-1. Dump the new bindings from the custom Godot build.
+> G++ and Clang++ are our recommended compilers for MacOS
 
-```shell
-cd local/copy/of/godot/source
-.\bin\godot.xxx --headless --dump-gdextension-interface --dump-extension-api
-```
+1. Prepare script for execution: ```chmod 755 build_libs_mac.sh```
+2. Run ```. ./build_libs_mac.sh Release```.
+3. Run ```scons platform=osx target=release```.
 
-2. Build the plugin along with the godot-cpp library.
+### Debug build
 
-```
-scons platform=<platform> target=editor generate_bindings=yes dev_build=yes -j 6
-```
+Replace `Release` with `Debug` and `release` with `debug` in the above instructions for a debug build. You will also have to do the same in the paths mentioned in `demo/git_api.gdnlib` before opening the demo project in Godot.
 
-> You only need to build godot-cpp once every change in the GDExtension API, hence, `generate_bindings=yes` should only be passed in during the first time after generating a new GDExtension API dump.
+### Bleeding Edge Builds
 
-3. Open the project provided inside `demo/` in the custom Godot build.
+> This section onwards is only meant to be used by developers.
 
-To view more options available while recompiling godot-git-plugin, run `scons platform=<platform> -h`.
+Most of the times when new features are being worked on for the Godot VCS Integration, this requires us to make changes in Godot along with this plugin. Thus, this means we need to manually generate the GDNative API from these newer Godot builds and then use them with godot-cpp.

+1. Generate `api.json` from Godot executable: `godot --gdnative-generate-json-api api.json`
+2. Change directory to `godot-cpp`: `cd godot-cpp`
+3. Build the C++ bindings: `scons platform=<platform> target=<target> generate_bindings=yes bits=64 use_custom_api_file=yes custom_api_file=<path/to/api.json> -j <number of CPUs>`
+4. Change directory up one level: `cd ..`

+
+`libgit2` is a portable, pure C implementation of the Git core methods
+provided as a linkable library with a solid API, allowing to build Git
+functionality into your application.  Language bindings like
+[Rugged](https://github.com/libgit2/rugged) (Ruby),
+[LibGit2Sharp](https://github.com/libgit2/libgit2sharp) (.NET),
+[pygit2](http://www.pygit2.org/) (Python) and
+[NodeGit](http://nodegit.org) (Node) allow you to build Git tooling
+in your favorite language.
+
+`libgit2` is used to power Git GUI clients like
+[GitKraken](https://gitkraken.com/) and [gmaster](https://gmaster.io/)
+and on Git hosting providers like [GitHub](https://github.com/),
+[GitLab](https://gitlab.com/) and
+[Azure DevOps](https://azure.com/devops).
+We perform the merge every time you click "merge pull request".
+
+`libgit2` is licensed under a **very permissive license** (GPLv2 with a special
+Linking Exception).  This basically means that you can link it (unmodified)
+with any kind of software without having to release its source code.
+Additionally, the example code has been released to the public domain (see the
+[separate license](examples/COPYING) for more information).

+
+Quick Start
+===========
+
+**Prerequisites** for building libgit2:
+
+1. [CMake](https://cmake.org/), and is recommended to be installed into
+   your `PATH`.
+2. [Python](https://www.python.org) is used by our test framework, and
+   should be installed into your `PATH`.
+3. C compiler: libgit2 is C90 and should compile on most compilers.
+   * Windows: Visual Studio is recommended
+   * Mac: Xcode is recommended
+   * Unix: gcc or clang is recommended.
+
+**Build**
+
+1. Create a build directory beneath the libgit2 source directory, and change
+   into it: `mkdir build && cd build`
+2. Create the cmake build environment: `cmake ..`
+3. Build libgit2: `cmake --build .`
+
+Trouble with these steps?  Read our [troubleshooting guide](docs/troubleshooting.md).
+More detailed build guidance is available below.
+

+include as much information as possible.  If possible, provide sample code
+that illustrates the problem you're seeing.  If you're seeing a bug only
+on a specific repository, please provide a link to it if possible.
+
+We ask that you not open a GitHub Issue for help, only for bug reports.
+
+**Reporting Security Issues**
+
+Please have a look at SECURITY.md.
+
+What It Can Do
+==============
+
+libgit2 provides you with the ability to manage Git repositories in the
+programming language of your choice.  It's used in production to power many
+applications including GitHub.com, Plastic SCM and Azure DevOps.
+
+It does not aim to replace the git tool or its user-facing commands. Some APIs
+resemble the plumbing commands as those align closely with the concepts of the
+Git system, but most commands a user would type are out of scope for this
+library to implement directly.
+
+The library provides:
+
+* SHA conversions, formatting and shortening
+* abstracted ODB backend system
+* commit, tag, tree and blob parsing, editing, and write-back
+* tree traversal
+* revision walking
+* index file (staging area) manipulation
+* reference management (including packed references)
+* config file management
+* high level repository management
+* thread safety and reentrancy
+* descriptive and detailed error messages
+* ...and more (over 175 different API calls)
+
+As libgit2 is purely a consumer of the Git system, we have to
+adjust to changes made upstream. This has two major consequences:
+
+* Some changes may require us to change provided interfaces. While we try to
+  implement functions in a generic way so that no future changes are required,
+  we cannot promise a completely stable API.
+* As we have to keep up with changes in behavior made upstream, we may lag
+  behind in some areas. We usually to document these incompatibilities in our
+  issue tracker with the label "git change".
+
+Optional dependencies
+=====================
+
+While the library provides git functionality without the need for
+dependencies, it can make use of a few libraries to add to it:
+
+- pthreads (non-Windows) to enable threadsafe access as well as multi-threaded pack generation
+- OpenSSL (non-Windows) to talk over HTTPS and provide the SHA-1 functions
+- LibSSH2 to enable the SSH transport
+- iconv (OSX) to handle the HFS+ path encoding peculiarities
+
+Initialization
+===============
+
+The library needs to keep track of some global state. Call
+
+    git_libgit2_init();
+
+before calling any other libgit2 functions. You can call this function many times. A matching number of calls to
+
+    git_libgit2_shutdown();
+
+will free the resources.  Note that if you have worker threads, you should
+call `git_libgit2_shutdown` *after* those threads have exited.  If you
+require assistance coordinating this, simply have the worker threads call
+`git_libgit2_init` at startup and `git_libgit2_shutdown` at shutdown.
+
+Threading
+=========
+
+See [threading](docs/threading.md) for information
+
+Conventions
+===========
+
+See [conventions](docs/conventions.md) for an overview of the external
+and internal API/coding conventions we use.
+
+Building libgit2 - Using CMake
+==============================
+
+Building
+--------
+
+`libgit2` builds cleanly on most platforms without any external dependencies.
+Under Unix-like systems, like Linux, \*BSD and Mac OS X, libgit2 expects `pthreads` to be available;
+they should be installed by default on all systems. Under Windows, libgit2 uses the native Windows API
+for threading.
+
+The `libgit2` library is built using [CMake](<https://cmake.org/>) (version 2.8 or newer) on all platforms.
+
+On most systems you can build the library using the following commands
+
+	$ mkdir build && cd build
+	$ cmake ..
+	$ cmake --build .
+
+Alternatively you can point the CMake GUI tool to the CMakeLists.txt file and generate platform specific build project or IDE workspace.
+
+Running Tests
+-------------
+
+Once built, you can run the tests from the `build` directory with the command
+
+	$ ctest -V
+
+Alternatively you can run the test suite directly using,
+
+	$ ./libgit2_clar
+
+Invoking the test suite directly is useful because it allows you to execute
+individual tests, or groups of tests using the `-s` flag.  For example, to
+run the index tests:
+
+    $ ./libgit2_clar -sindex
+
+To run a single test named `index::racy::diff`, which corresponds to the test
+function [`test_index_racy__diff`](https://github.com/libgit2/libgit2/blob/master/tests/index/racy.c#L23):
+
+    $ ./libgit2_clar -sindex::racy::diff
+
+The test suite will print a `.` for every passing test, and an `F` for any
+failing test.  An `S` indicates that a test was skipped because it is not
+applicable to your platform or is particularly expensive.
+
+**Note:** There should be _no_ failing tests when you build an unmodified
+source tree from a [release](https://github.com/libgit2/libgit2/releases),
+or from the [master branch](https://github.com/libgit2/libgit2/tree/master).
+Please contact us or [open an issue](https://github.com/libgit2/libgit2/issues)
+if you see test failures.
+
+Installation
+------------
+
+To install the library you can specify the install prefix by setting:
+
+	$ cmake .. -DCMAKE_INSTALL_PREFIX=/install/prefix
+	$ cmake --build . --target install
+
+Advanced Usage
+--------------

+- `CMAKE_INSTALL_LIBDIR`: Where to install libraries to.
+- `CMAKE_INSTALL_INCLUDEDIR`: Where to install headers to.
+- `BUILD_SHARED_LIBS`: Build libgit2 as a Shared Library (defaults to ON)
+- `BUILD_CLAR`: Build [Clar](https://github.com/vmg/clar)-based test suite (defaults to ON)
+- `THREADSAFE`: Build libgit2 with threading support (defaults to ON)
+
+To list all build options and their current value, you can do the
+following:
+
+	# Create and set up a build directory
+	$ mkdir build
+	$ cmake ..
+	# List all build options and their values
+	$ cmake -L
+
+Compiler and linker options
+---------------------------
+
+CMake lets you specify a few variables to control the behavior of the
+compiler and linker. These flags are rarely used but can be useful for
+64-bit to 32-bit cross-compilation.
+
+- `CMAKE_C_FLAGS`: Set your own compiler flags
+- `CMAKE_FIND_ROOT_PATH`: Override the search path for libraries
+- `ZLIB_LIBRARY`, `OPENSSL_SSL_LIBRARY` AND `OPENSSL_CRYPTO_LIBRARY`:
+Tell CMake where to find those specific libraries
+
+MacOS X
+-------
+
+If you want to build a universal binary for Mac OS X, CMake sets it
+all up for you if you use `-DCMAKE_OSX_ARCHITECTURES="i386;x86_64"`
+when configuring.
+
+Android
+-------
+
+Extract toolchain from NDK using, `make-standalone-toolchain.sh` script.
+Optionally, crosscompile and install OpenSSL inside of it. Then create CMake
+toolchain file that configures paths to your crosscompiler (substitute `{PATH}`
+with full path to the toolchain):
+
+	SET(CMAKE_SYSTEM_NAME Linux)
+	SET(CMAKE_SYSTEM_VERSION Android)
+
+	SET(CMAKE_C_COMPILER   {PATH}/bin/arm-linux-androideabi-gcc)
+	SET(CMAKE_CXX_COMPILER {PATH}/bin/arm-linux-androideabi-g++)
+	SET(CMAKE_FIND_ROOT_PATH {PATH}/sysroot/)
+
+	SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
+	SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
+	SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
+
+Add `-DCMAKE_TOOLCHAIN_FILE={pathToToolchainFile}` to cmake command
+when configuring.
